ok - i dont like passing all tyhe funcs as params. please do it this way:
EAPI Elm_Genlist_Item_Class *elm_genlist_item_class_new(void);
EAPI void elm_genlist_item_class_free(Elm_Genlist_Item_Class
*itc);
EAPI void elm_genlist_item_class_ref(Elm_Genlist_Item_Class
*itc);
EAPI void elm_genlist_item_class_unref(lm_Genlist_Item_Class
*itc);
now ADD a version field to the top of the current item class and a refcount
number. ref and unref just add and sub from the refcount number - as does free
(free can just call unref - i'm only adding it to pair with new). new just
calloc()'s the item class struct and fills in version # and sets refcount to 1.
if ref goes to 0 then free the class.
now... every genlist item that uses this class should ref() the class.every
item from a genlist thats deleted should unref() it. now the issue ca be solved
by unref or free()ing the item classes u created for use in the gnelist on del
of the genlist obj (u can attach a del callback). they will not be freed then
until refs hit 0, but on obj del they can set func ptr's to null thus making it
safe.
